It takes two

摘要

AN ADVANCED FAN DRIVE THAT MEETS THE NEEDS OF VOCATIONAL AND OFF-HIGHWAY VEHICLES ALIKE USES A HIGHLY EFFECTIVE, DURABLE AND EASILY ADAPTABLE TWO-SPEED SOLUTION TO INCREASE FUEL EFFICIENCY WHILE ENHANCING ENGINE PERFORMANCE Various factors influence the features certain technologies have to offer commercial vehicles. For instance, because they maximize fuel economy by minimizing fan engagements for over-the-road applications, on/off fan drive systems are ideal for many long-haul applications - yet the requirements for fan drives used for severe-duty vocational and off-highway applications are very different. In construction vehicles or municipal trucks, on/off fan drives may even dis/engage every 90 seconds, which can greatly increase operating noise and clutch liner wear.
